Application filed November 29, 1920. Serial No. 426,946.

T 0 all to 7mm "it may concern Be it known that I, W ALTER Gr. HoLMns, am a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Knockdown Dental and Surgical Tables; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improved surgical and dental instrument table of the type used in connection with sterilizers, and to such ends, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in theclaims.

Tables of the above character usually have rectangular frames, so that the tables can be shipped only in rectangular crates or boxes within which there is a great deal of waste space. As an important feature of my invention, I construct the table with a frame that is approximately triangular, so that it may be contained within a crate or box that is triangular in cross section. By such formation of the frame in connection with detachable arms or brackets for supporting a table top, shelf and sterilizer, I provide a complete table and equipment .021- pable of being disassembled and packed in a triangular crate that has only approximately one-half the internal space of a rectangular box required to contain a rectangular framework. Moreover, these triangular crates, for the purpose of shipment, may be interlapped so that the several crates are contained within spaces between othercrates,

, thus packing the boxes in solid formation within space that is only approximately onehalf of that required to contain rectangular boxes containing the same or other table structures. Thus, there is a saving, in the first place, in the crates, with a resulting saving in space required for storage or shipping of the filled crates. Of course, the freight rate, per box, will be much less with the triangular boxes than with the larger square boxes, for the reason that freight rates are based not only on weight, but also on space occupied Within a car.-.

The table, aside from the advantages above noted, involves other novel and important features which relate to the erected table itself.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

F 1g. 1 is a perspective showing the complete table and sterilizer supported therefrom;

Fig. 2 is a perspective showing the table with some of the elements thereof detached from the framework; I

Fig. 3 is a front elevation of the sterilizer;

Fig. f is a fragmentary section taken on the line 4-4 of Fig. 1; and

Fig. 5 is a fragmentary section taken on the line 5-5 of Fig. 1.

The table frame comprises approximately triangular end pedestals 8, rigidly connected by upper and lower cross bars 9 and 10. The upper end portions of the pedestals 8, above the upper cross bar 9, are preferably formed by upward extensions of the main tubes of said pedestals, and to the upper ends thereof, preferably by threaded engagement, are rigidly but detachably secured cross arms 11.

The cross arms 11, at their ends, (see particularly Fig. 4), are provided with inset rubber blocks 12, upon which the table top 13, preferably a glass plate, is loosely placed. To prevent forward displacement of the top plate 18, the cross arms 11, at their front ends, are provided with small metallic retaining clips 14 held thereto by screws 14 or otherwise, and terminated preferably slightly below the upper surface of said top plate. Rearward displacement of the top plate 13 is prevented by a metallic back rail 15, preferably formed of flat bar metal and having downturned ends rigidly but detachably secured to the rear ends of the cross arms 11 by screws 15 Endwise displacement of the top plate 18 is prevented by end rails 16 of substantially the same construction as the back rail 15 and having their downturned ends rigidly but detachably secured to the end portions of the cross arms 11 by screws 16. The back and end rails 15 and 16 also prevent articles, such as instrument trays or the like, from being pushed off the back and sides of the top plate.

. To support a shelf 17, which is also preferably a glass plate but somewhat more nar- I row in a forward and rearward direction than the top plate 13, I provide bar-like metallic brackets 18 provided, at their intermediate portions, with yoke-like clamps 19, preferably secured thereto by small nutequipped bolts 20, by means of which said yoke's may be clamped rigidly onto the up-' per cross bar 9. At their ends, saidbrackets 18 have upturned lips 21, which hold the shelf 17 against displacement. Soft rubber buttons 22, applied to the brackets 18,near their ends, serve as direct supports for the shelf l7.

The numeral 23 indicates, as an entirety, the sterilizer, such as used by dentists and surgeons for sterilizing their instruments, the same, as shown, bein a rectangular boxlike structure having a hinged cover and certain other devices not necessarily considered for the purposes of this case; To support this sterilizer from the table, I provide an elbow-like bracket 24, which, at its lower end, has a clamp formed bya fixed jaw 25 and a movable jaw 26, the two jaws being connected by a clamping screw 27, (see particularly Figs. 1, 3 and 5). These'jaws 25 and 26 are adapted to be firmly but detach ably clamped onto the upper endof one of the triangular end brackets 8.

The sterilizer is preferably of the electrically heated type and is shown as provided with a cable 28, containing wires adapted to be connected to a socket either directly or through the base of a light bulb 29.

The importance of this invention must be obvious from the foregoing description and statements made.

What I claim is: j

1. A dental orsurgical table including a frame having supporting end members, a cross bar connecting said end members, cross arms on the end members and cross bar, and

3. A dental or surgical table including a frame having approximately triangular end pedestals, across bar connecting the end pedestals at their upper ends, said end pedestals having extensions above the cross bars, cross arms on the upper ends of the pedestal extensions, a back railconnecting the cross arms, side rails attached to the cross arms, a

and a table top removably supported on the cross arms, said back and siderails being extended above the table topexcept attheir ends where they act as stops for the table top.

a. A dental or surgical table including a" frame having approximately triangular end pedestals, a cross bar connecting the end pedestals at their upper ends, said end pedestals having extensions above the cross bars, cross arms on the upper ends of the pedestal extensions, a back rail connecting the cross arms, side rails attached to the cross arms, a table top removably supported on the cross arms, said back andside rails being extended above the table top except at their ends where they act as stops for the table top, and clips attached to the front ends of the cross arms below the upper surface of the table top andaffording a stop therefor.

In testimony whereof I aflix my si nature.
